The Sesame 5 and Sesame Touch Pro are also being sold as a set. I am selling these because they are no longer needed due to a move. They are very convenient, and once registered, you can lock and unlock the door by holding up a smartwatch. There is also a fingerprint sensor, so you can unlock the door with your fingerprint. You can also unlock the door with cards like Suica and PASMO. I had no problems using them. There are some minor scratches. Please refrain from purchasing if you are sensitive to used items. Thank you for your understanding. On Amazon, the set is priced at 11,592 yen, so I have set a trial price that is cheaper than that. Thank you for your consideration.
